Abstract
Se suministran dializadores que poseen un diseno de cabezal mejorado que brinda un flujo de fluido mejorado, es decir, sangre hacia el interior del dializador y específicamente al haz de fibras. El cabezal de entrada del dializador incluye un cuerpo que define, al menos parcialmente, un extremo del dializador. El cabezal de entrada incluye un canal de entrada que aporta comunicacion del fluido desde el exterior del dializador hacia el interior del dializador; el canal de entrada define una direccion de flujo de fluido que es axial al haz de fibras ubicado en el interior del dializador. El dializador también incluye al menos una pieza para modificar la direccion del flujo de un fluido a medida que sale del canal de salida. Asimismo, se proporcionan métodos para suministrar diálisis.
